NOTES:
1. VDD, V0, VOUT, V1 to V4 and VEXT are based on VSS = 0V.
2. Voltages V0 V1 V2 V3 V4VSS must always be satisfied.(VLCD = V0 VSS)
3. If supply voltage exceeds its absolute maximum range, this LSI may be damaged permanently. It is desirable to use this LSI under electrical characteristic conditions during general operation. Otherwise, this LSI may malfunction or reduced LSI reliability may result.




Description

The KS0741 is a driver & controller LSI for 4-level gray scale graphic dot-matrix liquid crystal display systems. It contains 128 segment and 129 common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral Interface(SPI) or 8-bit parallel display data and stores in an on-chip display data RAM of 128 x 129 x 2 bits. It performs display data RAM read/write operation with no external operating clock to minimize power  onsumption. In addition, because it contains power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.
